Siemens' vision is to to deliver engineering simulation solutions that drive product performance decisions across the complete product lifecycle. Siemens executes this vision by building upon a simulation heritage which spans over 40 years and encompasses well-known CAE brands like Nastran and SDRC I-deas. Siemens has strengthened and expanded upon the technologies from its long simulation legacy and has brought them together to deliver the next generation of world-class CAE software.

Best-in-Class Analysis Modeling

Create analysis models faster using powerful tools such as direct multi-CAD geometry editing powered by synchronous technology, and a full suite of commands for geometry idealization and meshing.

Seamless Associativity with CAD Geometry

CAE models are associated with the original CAD geometry, and easily update your analysis models whenever the design changes.

NX (Unigraphics) CAE seamlessly connects with Teamcenter to enable effortless storage, re-use, and sharing of simulation data, knowledge, and processes with more people throughout your organization.

Focus on System-Level Modeling and Simulation

Efficiently build and manage FE assemblies through a unique, multi-level approach that can allow for multiple instances of the same FE component.

Fast and Powerful Solvers

Solve large models efficiently with the industry's leading finite element solver, NX Nastran.

Open, Multi-Solver Support

Export analysis models and import simulation results for other common finite element solvers including Abaqus, Ansys, LS-Dyna, and MSC Nastran.

NX (Unigraphics) for Simulation (NX CAE) Benefits

Increase Simulation Productivity by up to 70 Percent

Increasing simulation productivity speeds up your entire product development cycle, allowing you to bring your products to market faster. More efficient simulation processes also lead to more innovation, by allowing more design-analysis iterations that can be used to test more design alternatives, and make critical design decisions earlier.

Increase Product Quality

By simulating real-world conditions, you get a clearer understanding of how your product will perform. NX solutions for simulation facilitate easier trade-off analysis across multiple disciplines, allowing you to develop more robust products. Requirements tracking and reporting capabilities allow you to quickly gauge if your product is performing to specification.

Reduce Product Development and Warranty Costs

Faster simulation processes means analysis results are fed back to design earlier, leading to a reduction in costly, late design change orders. Additionally, correlating simulation with physical testing provides more confidence in your analysis, so you reduce costly physical prototypes. And with increased product quality, you save on potential warranty costs.
